FRANK STINER AND ESEK R. DARLING, OF NORTH MONSO, ASSIGNORS OF ONE-THIRD TO CHARLES ATWATER, OF PITTSFIELD, MASSACHUSETTS.

CARTRIDGWEfSHELL.

To aZZ whom, t may concern: 4 Beit known that we, FRANK Sri-NER and EsEK R. DARLING, ot North Monson, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Cartridge-Shells, of which the following is a specification.

This invention consistsin a cartridge shell having its inner periphery coated with any suitable adhesive material which is hard and impervious to air when dry, not easily burned, andadhesive when moistened, the object of the invention being to enable the wads of the cartrid'ge to be fastened by simply moistening the inner surface of the shell, and to make the shell capable of being repeatedly used, as well as to improve it in other respects, allot' whigh wewvillno'w proceed to describe. z

Of the accompanying drawings, forming a part of this specification, Figure 1 represents -a longitudinal section of our improved cartridge-shell. Fig. 2 represents a longitudinal section of a complete cartridge.

In carrying out our invention we take a car# tridge-shell, a, of paper or other like mate. rial, and of ordinary or any suitable construction, and apply to its inner surface a coating, b, of any suitable adhesive material, such as mucilage or other material which hardens and becomes impervious to air when dry and becomes sticky when wet, and will not readily ignite and burn away. Said coating preferably extends over the entire inner surface of the shell.

points where said wads are to be located, and thewads are then inserted, their edges `coming in contact wit-h'the adhesive coating, and `being held by said coating when the latter dries or hardens.

Heretofore cartridge wade have been gummed on their peripheries to enable them to adhere to the shell,the gum; being first moist cned; but we are not aware that a cartridgeshell has ever been gummed or internally coated with an adhesive and comparatively non-combustible: materiaiin the manner above described.

When the wads c are -to be secured i, in the shell, the coating b is moistened at the SPECIFICATION forming part of Lettere Patent No..377.816, dated February 14, 1888.

' Application tiled September 19, 1887. Serial No. 250,054. (No model.)

The following are'thecbief advantages of blistered by the explosion of the powder, s o that the same shell can be used for a greater number of discharges than ungummed paper shellsf which-*after encor two'rings become so blistered as to be unfit for use; fourthly,

the gummed surface, being within the shell,' cannot become moistened by contact with wet lingers or other external objects, while gum med wads are quite liable to be so moistencd.

We are aware that. it has been proposed to coat a metallic cartridge-shell'internally with collodion, which is a highly-combustible material, and would therefore .be destroyed by a single discharge of the cartridge. yOur coat-` ing, being practically non-combustible,enables the `shell to be repeatedly used without recoatt ing and without blistering.

We claim- A non-metallic cartridge-shell having an in- .'ternal coating of adhesive and practically noncombustible material, whereby the wads may .be secured, said coating enabling the shell 'to be repeatedly used without blistering, as sct forth.

In testimony whereof we have signed our names to this specification, in the presence ot two subscribingwitnesses, this 12th day of September, A. D. 1887.
